This article is about how to solve the problem of 'single quotation marks in strings when oracle inserts string data. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Use insert into (field1,field2...) Values ('val1','val2'...) An error is reported if there are single quotation marks in the value.

How to deal with it: determine whether the val1,val2 contains single quotation marks, and if so, replace the single quotation marks' with two single quotation marks'.

Organize fields and field values into a HashTable, and then abstract a function getSqlByHashTable () that organizes sql statements:

HashTable ht = new HashTable (); ht.add (field1,val1); ht.add (field2,val2); ht.add (field3,val3);. Public string getSqlByHashTable (string tablename,HashTable ht) {StringBuilder sb=new StringBuilder (); sb.append ("insert into" + tablename+ "("); StringBuilder fsb=new StringBuilder (); StringBuilder vsb=new StringBuilder (); foreach (var key in ht.Keys) {fsb.append (key+ ","); string value=ht [key]; if (value.trim ()) = ") {value=" } else {if (value.Contains ("'")) {value=value.replace ("'", "'");} value= "'" + value+ "'";} vsb.append (value+ ",");} sb.append (fsb.toString (). Substring (0Med fsb.toString (). Length-1)) Sb.append (") values ("); sb.append (vsb.toString (). Substring (0dsb.toString (). Length-1)); sb.append (")"); return sb.toString ();} Thank you for reading!
